Examples

The following code example creates a WebProxy object and calls this method to check whether the bypass list is properly set.

public static WebProxy CreateProxyAndCheckBypass(bool bypassLocal)
{
    // Do not use the proxy server for Contoso.com URIs.
    string[] bypassList = new string[]{";*.Contoso.com"};
    WebProxy proxy =  new WebProxy("http://contoso",
        bypassLocal,
        bypassList);

    // Test the bypass list.
    if (!proxy.IsBypassed(new Uri("http://www.Contoso.com")))
    {
        Console.WriteLine("Bypass not working!");
        return null;
    }
    else
    {
        Console.WriteLine("Bypass is working.");
        return proxy;
    }
}

Remarks

The IsBypassed method is used to determine whether to bypass the proxy server when accessing an Internet resource.

The BypassProxyOnLocal and BypassList properties control the return value of the IsBypassed method.

IsBypassed returns true under any of the following conditions:

• If BypassProxyOnLocal is true and host is a local URI. Local requests are identified by the lack of a period (.) in the URI, as in http://webserver/.

• If host matches a regular expression in BypassList.

• If Address is null.

All other conditions return false.
